An overview of head tracking integral imaging three-dimensional display using smart pseudoscopic-to-orthoscopic conversion
2017
We overview a previously reported head tracking integral imaging three-dimensional (3D) display to extend viewing angle accommodated to a viewer's position without the crosstalk phenomenon. A head detection system is applied to obtain the head position and rotation of a viewer, and a new set of elemental images is then computed using the smart pseudoscopic-to-orthoscopic conversion (SPOC) method for head tracking 3D display. Experimental results validate the proposed method for high quality 3D display with large viewing angle.
Toward 3D integral-imaging broadcast with increased viewing angle and parallax
2018
Abstract We propose a new method for improving the observer experience when using an integral monitor. Our method permits to increase the viewing angle of the integral monitor, and also the maximum parallax that can be displayed. Additionally, it is possible to decide which parts of the 3D scene are displayed in front or behind the monitor. Our method is based, first, in the direct capture, with significant excess of parallax, of elemental images of 3D real scenes. From them, a collection of microimages adapted to the observer lateral and depth position is calculated. Finally, an eye-tracking system permits to determine the 3D observer position, and therefore to display the adequate microim…
3D integral imaging with optical processing
2008
Integral imaging (InI) systems are imaging devices that provide auto-stereoscopic images of 3D intensity objects. Since the birth of this new technology, InI systems have faced satisfactorily many of their initial drawbacks. Basically, two kind of procedures have been used: digital and optical procedures. The "3D Imaging and Display Group" at the University of Valencia, with the essential collaboration of Prof. Javidi, has centered its efforts in the 3D InI with optical processing. Among other achievements, our Group has proposed the annular amplitude modulation for enlargement of the depth of field, dynamic focusing for reduction of the facet-braiding effect, or the TRES and MATRES devices…
New development opportunities for the craft brewing segment: the case study of a micro-malthouse
2017
In Italy in the past few years, the number of small breweries penetrating the craft beer sector has grown exponentially. Craft producers intend to give a strong added value and a local character to their production in different ways. One of these is the use of malt derived from small batches of local cereals and pseudo cereals. The aim of this study is the assessment of investment profitability, through a cost-benefit analysis (CBA), for a compact and a modular micro-malting plant in Sicily (Southern Italy). The CBA for a micro-malthouse was carried out considering both installation and operating costs. Net present value (NPV), discounted benefit-cost ratio (DBCR) and internal rate of retur…
Impact of covid-19 in gynecologic oncology: A nationwide italian survey of the sigo and mito groups
2020
Objective Coronavirus disease 2019 (COVID-19) has caused rapid and drastic changes in cancer management. The Italian Society of Gynecology and Obstetrics (SIGO), and the Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) promoted a national survey aiming to evaluate the impact of COVID-19 on clinical activity of gynecologist oncologists and to assess the implementation of containment measures against COVID-19 diffusion. Methods The survey consisted of a self-administered, anonymous, online questionnaire. The survey was sent via email to all the members of the SIGO, and MITO groups on April 7, 2020, and was closed on April 20, 2020. Results Overall, 604 particip…
Systematic Position of the Fossil Burrower Bug Eocenocydnus lisi Popov, 2019 (Hemiptera, Heteroptera, Cydnidae) Revealed by a Parallel/Cross-Eyed Vie…
2022
The fossil burrower bug Eocenocydnus lisi described from the Late Eocene of the Isle of Wight, UK, is analysed using a parallel, cross-eyed viewing method. The species, tentatively placed in the subfamily Sehirinae, is redescribed and its systematic position is discussed. Newly recovered morphological characteristics allow it to be placed in the tribe Cydnini of the subfamily Cydninae.
Enhancing citizen response to crises through communication : investigating expert views
2015
The purpose of this paper is to clarify how citizen response to crises is currently being enhanced, and how it might be increased, by emergency response organisations in member states of the European Union via communication strategies and tools. Data were gathered via an online questionnaire directed at emergency management and crisis communication experts working in the field of crisis response. The experts were drawn from the database of an international conference. The results indicate that while the importance of involving citizens in crisis response is generally acknowledged, the implementation of such activities is often fragmented. Although some initiatives are under way, coherent st…
Business Intelligence and Analytics in Small and Medium-sized Enterprises: A Systematic Literature Review
2017
Despite much interest in business intelligence and analytics (BI&A), empirical research shows that small and medium-sized enterprises (SMEs) are still lagging behind in the proliferation of BI&A. However, there are no studies found on literature reviewing research on BI&A in SMEs. This paper collects, categorizes, synthesizes, and analyzes 62 articles related to BI&A in SMEs. The identified research topics being addressed in BI&A include: BI&A components, BI&A solutions, Mobile BI&A, Cloud BI&A, BI&A application, BI&A adoption, BI&A implementation, and BI&A benefits. Further, research gaps and directions for future research are presented to facilitate the progression of BI&A in SMEs researc…
Third-Person Perception of Television-Viewing Behavior
2000
Both conceptually and empirically, the third-person effect has been confined to the effects of mass communication (people tend to believe others are more susceptible to media influences than they are themselves, and people tend to act accordingly). This study investigated whether this phenomenon extends to the perception of other people's media use, and whether it can be explained by a general tendency to underrate the education of others. We interviewed a sample of 200 adults in south-western Germany, focusing on television-viewing behavior. As hypothesized, people tend to perceive others as more inclined toward undesirable viewing behaviors. We also hypothesized and found that third-perso…
An internet-based approach for lifestyle changes in patients with NAFLD: Two-year effects on weight loss and surrogate markers
2018
Background & Aims Interventions aimed at lifestyle changes are pivotal for the treatment of non-alcoholic fatty liver disease (NAFLD), and web-based programs might help remove barriers in both patients and therapists. Methods In the period 2010–15, 716 consecutive NAFLD cases (mean age, 52; type 2 diabetes, 33%) were treated in our Department with structured programs. The usual protocol included motivational interviewing and a group-based intervention (GBI), chaired by physicians, dietitians and psychologists (five weekly meetings, n = 438). Individuals who could not attend GBI entered a web-based intervention (WBI, n = 278) derived from GBI, with interactive games, learning tests, motivati…
